CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 490,033, dated January 17, 1893.

Application filed August 3, 1892.

To all whom it may concern.-

Be it known that 1, JAMES S. MOORE, acitizen of the United States,residing at Sullivan, in the county of Sullivan and State of Indiana, have invented a new and useful Improvement in Gan-Filling Machines, of which the following is a specification.

My invention relates to an improvement in a can-filling machine, for which Letters Patent No. $68,888, were issued to me February 16, 1892.

The objects of my present improvements are, to simplify the salt-dropping mechanism; to provide means for controlling the flow of material from the filling-hopper, and to provide means for directing the overflow of liquid from the can during the process of filling, all as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure 1 represents a side elevation of the complete machine. Fig. 2 represents avertical section of the hopper and plunger, at c Fig. 1. Fig. 3 represents, on an enlarged scale, a central vertical section of the saltchamber and the salt-dropping mechanism. Fig. 4 represents a plan at -a Fig. 3. Fig. 5 represents a plan at -b Fig. 3. Fig. 6 represents a plan, on an enlarged scale, of the under side of the face-plate which is secured to the lower end of the hopper-spout, and against which the top of the can rests when in position for filling. Fig.7 represents a vertical longitudinal section of said face-plate. Fig. 8 represents a vertical transverse section of the same.

In the drawings, A,indicates the can-trough into which the cans are delivered through a vertical chute B. C, is the salt-chamber beneath which the cans pass as they traverse the can-trough; being pushed forward successively by the oscillation of the bell-crank lever D. Lever D is oscillated by means of a lever, E, pivoted upon the shaft F, and operated by means of the cam G, which is secured to the shaft 11, so as to rotate therewith, the shaft being driven by means of a pinion, I, which is secured to the driving shaft F and a gear-wheel, J, which is secured to shaft H. Lever E is connected also to the vertical rod K, to the upper end of which plunger L is se- Serial No. 442,038. (No model.)

cured. M, is a hopper terminating in aspout N, beneath which the cans are held, successively, by jaws 0. All of these above described parts are similar in their general arrangement, and operation to like parts shown and described in my above mentioned letters patent, and need not be here further described.

For the purpose of controlling the flow of the material from hopper M to the spout N, I secure to the fixed bearing, P, in which the plunger L slides,acylindrical sleeve, R,which is vertically adjustable upon the bearing so as to project to a greater or less extent below the lower end of the plunger when the plunger is at the upper limitof its stroke, thereby obstructing the entrance to the spout to any desired extent.

For the purpose of delivering a measured amount of salt into each can as it passes beneath the salt chamber, said chamber is constructed with two bottoms, S, and T, having a narrow space, U, between them. Bottom T is provided with a short spout, V, which communicates with space U and with the interior of the can-trough. The bottom S, is provided with a small opening, I, which is arranged at one side of the entrance to spout V. Fitting nicely between bottoms S and T, is a sliding valve 2, having a port, 3, extending vertically through it. Valve 2 is provided with a valverod, 4., which projects through the side of the chamber and is provided at its outer end with a longitudinal slot 5. Arranged to slide on the upper surface of bottom S, across the opening 1, is an agitator, 6, which is for the purpose of agitating the salt and insuring its entrance through opening 1 into the port '3, of the valve. Agitator 6 is provided with connecting-rod 7, which projects through the side of the salt-chamber and is attached to a vertical bar 8, to which is also attached a sliding plate, 9, which closes the mouth of spout N during the removal of the filled cans and the coming of an empty can into position beneath the spout. Connecting-rod 7, is provided on its under side with a pin 10, which projects into the slot 5 in valve-rod 4. Bar 8 is given a horizontally reciprocating movement by means of a bell-crank lever, 11, pivoted upon shaft F and having one arm connected with bar 8, by means ofa connect ing rod 12, and engaging with the other arm the cam' 13, Which is secured to shaft H so as to turn therewith.

connected with the can-lifter, 14', in a common and Well known manner.

Forthe purpose of keeping the salt dry in chamber 0, valve 2, and spout V, and incna coil of pipe, 15, which is connected with a I source of steam-supply, (not shown).

. For the purpose of directing the overflow from the can, when being filled, into the Wastetrcugh, 16, I mount upon the front of the main-fran1e, beneath spoutN, a face-plate 17,

having upon its upper surface a circular flange, 19, adapted to receive the lower end of spout N; and having upon its under side, concentric with spout N, a flange 20, adapted I toenter the opening 21 in the'top of the can surrounded bya circular recess 23 of less diameter than the can, cut in the under face of the face-plate, and having, on opposite sides,

, lateral extensions 7 24, which extend beyond the periphery of the can, as shown in Fig. 8; the arrangement beingsuch that the'top' of the cauwhen in position forfilling, is in contact with the smooth undenface of. thefaceflanges 25, to. which areconnected vertical plate, except at those points which are opposite the recess 23,and its extensions. 7 The outerends of theextensions 2a, are closed by guides 26. I I I Plate 17 is provided with a horizontal slot 27, in which is mounted the sliding plate 9,

which operates as a valve to out off the flow of material from spout N, to the can.

The operation of the improved portions of my machine is as follows. The empty cans, having entered trough A through chute B, are pushed forward in succession by the oscillation of lever D, and, as a can comes to rest beneath the spout V, the vertical arm of lever 11 is thrown backward by the movement of cam 13, thus drawing bar 8 backward; the first part of its movement operating to slide agitator 6 across the opening 1 in the bottom of the salt chamber, thus insuring the filling with salt of the port 3, in valve 2. As soon The lower end of bar 8 is as pin 10, in connection-rod -7, traverses the length of slot 5, valve 2 is also pushed bacK- ward until its port 3 registers with spout the solid portion of the valve operating to close opening 1, and the salt being discharged from port 3, through spout V, into the can. The reverse movement of lever L,restores the 1 parts to the position as shown in Fig. 3. The

can having reached a position beneath the; faceplate 17 is held by lever 14, incontact with the under side of the face-plate, the

flange 2O entering looselyv the opening'in the top of the can- As the can is filled with material from spout N, the airfrom the can escapes through the opening in its top around flange '20 and into recess 23, the air carrying with it a portionof the liquid from the material with'which the can is being filled, which liquid, passing'into the extensions of recess 23, is conducted,'by vertical: guides 26.

into the waste-trough 15, thus avoiding the v I scatteringot the liquid about the machinery. 22, Figs. 7 and 8. Said flange 20 is of less diameter than the opening in the can, and is I claim as my invention;
